    McCULLOUGH, Judge.
    The North Carolina Rate Bureau (“Bureau”) appeals from order entered by the
    North Carolina Commissioner of Insurance (“Commissioner”) that rejected the
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    Bureau’s filed rate increases and imposed alternative rate changes. For the following
    reasons, we affirm the Commissioner’s order.
    I.      Background
    On 3 January 2014, the North Carolina Department of Insurance
    (“Department”) received the Bureau’s filing for revised homeowners’ insurance rates
    and revised homeowners’ insurance territory definitions (the “filing”). In the filing,
    the Bureau sought approval of an overall statewide average rate level change of
    +25.6%, with the filed rates varying between the newly defined territories.1 Broken
    down into categories, the filing included the following statewide rate increases: 24.8%
    for owners, 54.9% for tenants, and 50.0% for condominiums. The Bureau requested
    that the filed rates be applied to all new and renewal policies becoming effective on
    or after 1 August 2014.
    The same day the Department received the filing, the Commissioner issued a
    press release in which he noted that new homeowners’ insurance rates went into
    effect just six months prior in July 2013, expressed his displeasure with the filing,
    and indicated that the insurance companies should expect a full hearing on the
    matter because he would not entertain settlement negotiations.
    1  As indicated in a letter from the Bureau to the Commissioner accompanying the filing on
    3 January 2014, the overall statewide average rate level change initially sought in the filing was
    +25.3%. Yet, as indicated in a letter from the Bureau to the Commissioner accompanying amendments
    by the Bureau to the filing on 9 June 2014, 
    noted supra
    , the overall statewide average rate level change
    slightly increased to +25.6% as a result of amendments. To avoid confusion, we refer only to the rate
    changes identified in the Bureau’s amendments to the filing.
    -2-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    On 19 February 2014, the Commissioner issued a notice of hearing in which he
    set the matter for hearing to begin 6 August 2014, scheduled a prehearing conference
    for 24 July 2014, and identified issues with the filing. The Bureau responded to the
    notice by submitting amendments to the filing. In addition to a slight increase in the
    overall statewide average rate level change, those amendments included changes to
    the filed territory definitions in order to address concerns of the Department. On
    11 July 2014, the Commissioner granted a continuance pushing the commencement
    of the hearing back to 20 October 2014.           Pursuant to the continuance, the
    Commissioner also issued amendments to the notice of hearing on 14 July 2014.
    Those amendments noted the change in the hearing date and rescheduled the
    prehearing conference for 10 October 2014.
    Following the prehearing conference on 10 October 2014, the Commissioner
    entered a prehearing order with the consent of the Bureau and the Department. The
    matter came on for public hearing in Raleigh before Commissioner Wayne Goodwin
    on 20 October 2014. The hearing continued on 21, 27, 28, 29, 30, and 31 October 2014
    and 3, 5, 6, 11, and 12 November 2014. During the hearing, over fifty exhibits of
    prefiled testimony and documentary evidence and over two thousand pages of live
    testimony were offered for consideration.
    The Commissioner issued his order in the matter on 18 December 2014. The
    Commissioner subsequently amended the order on 22 December 2014 and
    -3-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    13 January 2015 to correct non-substantive typographical errors, miscalculations in
    exhibits, and an incorrect citation to an exhibit. In the order, the Commissioner
    accepted the Bureau’s amended revisions to the territory definitions, noting the
    Department had not objected to the amended revisions. The Commissioner, however,
    determined the Bureau failed to meet its burden of proof regarding its filed rate
    increases and, therefore, disapproved the filed rates. Instead of the Bureau’s filed
    rates that resulted in an overall statewide average rate level change of +25.6%, the
    Commissioner ordered rates that resulted in an overall statewide average rate level
    change of 0%. In reaching the 0% change, the Commissioner ordered rate increases
    for tenants and condominiums and decreases for owners. The ordered rates were to
    be effective 1 June 2015.
    The Bureau filed notice of appeal from the Commissioner’s order on
    16 January 2015.
    II.    Discussion
    On appeal, the Bureau seeks to have the Commissioner’s order declared null
    and void so that its filed rates and territory definitions become effective by operation
    of law. Yet, because the filed territory definitions were approved, the Bureau’s
    arguments on appeal focus on the rates and the allocation of those rates.
    Throughout the Bureau’s arguments on appeal, the Bureau directs this Court’s
    attention to the press release issued by the Commissioner on the day the Department
    -4-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    received the filing. The Bureau contends “[t]he defining theme of the [o]rder is that
    every decision announced within it was consistent with [the Commissioner’s]
    rejection of the [f]iling the day it was filed.” Specifically, the Bureau claims
    [t]he Commissioner rejected overwhelming and sometimes
    undisputed evidence of the Bureau.           He repeatedly
    accepted as credible testimony of Department witnesses
    unsupported by competent or material evidence and chose
    factors based on matters outside the record, all of which in
    the aggregate led to the result foretold by his press release
    – that homeowners insurers are not entitled to and should
    not have requested a rate increase regardless of the
    evidence of rate inadequacy.
    The Bureau further asserts that there are too many issues with the Commissioner’s
    order to address each issue on appeal; therefore, the Bureau asserts the following
    arguments challenging specific components of the ordered rates:                    (1) the
    Commissioner erred as a matter of law by ordering an underwriting profit provision
    that fails to meet legal and constitutional standards; (2) the Commissioner erred by
    rejecting the reinsurance provision filed by the Bureau and by selecting a provision
    that is unsupported by material and substantial evidence; (3) the Commissioner erred
    by reducing the filed value for modeled hurricane losses; and (4) the Commissioner
    erred by rejecting the filed allocation of the net cost of reinsurance and underwriting
    profit to geographic zones.
    Before reaching the merits of the issues, we dispel the Bureau’s suggestion that
    the Commissioner rejected the filing on the day the Department received it. The
    Commissioner’s review of a Bureau filing is governed by statute.
    -5-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    At any time within 50 days after the date of any filing, the
    Commissioner may give written notice to the Bureau
    specifying in what respect and to what extent the
    Commissioner contends the filing fails to comply with the
    requirements of this Article and fixing a date for hearing
    not less than 30 days from the date of mailing of such
    notice. Once begun, hearings must proceed without undue
    delay. At the hearing the burden of proving that the
    proposed rates are not excessive, inadequate, or unfairly
    discriminatory is on the Bureau. At the hearing the factors
    specified in [N.C. Gen. Stat. §] 58-36-10 shall be
    considered. If the Commissioner after hearing finds that
    the filing does not comply with the provisions of this
    Article, he may issue his order determining wherein and to
    what extent such filing is deemed to be improper and fixing
    a date thereafter, within a reasonable time, after which the
    filing shall no longer be effective. In the event the
    Commissioner finds that the proposed rates are excessive,
    the Commissioner shall specify the overall rates, between
    the existing rates and the rates proposed by the Bureau
    filing, that may be used by the members of the Bureau
    instead of the rates proposed by the Bureau filing. In any
    such order, the Commissioner shall make findings of fact
    based on the evidence presented in the filing and at the
    hearing. Any order issued after a hearing shall be issued
    within 45 days after the completion of the hearing. If no
    order is issued within 45 days after the completion of the
    hearing, the filing shall be deemed to be approved.
    N.C. Gen. Stat. § 58-36-20(a) (2015).        Although the Commissioner voiced his
    displeasure with the filing in the press release issued on the day the Department
    received the filing, it is clear the Commissioner did not reject the filing outright. The
    record shows the Commissioner followed the statutory procedure for reviewing the
    filing, which in the present case included a lengthy hearing and the consideration of
    extensive evidence. Even more telling, the Commissioner’s review resulted in the
    -6-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    approval of the filed territory definitions and changes to homeowners’ insurance
    rates, although not the filed rates sought by the Bureau. Consequently, this Court’s
    review is not influenced by the Commissioner’s press release.
    Standard of Review
    Just as the Commissioner’s review of the Bureau’s filing is governed by statute,
    so is this Court's review of the Commissioner’s order. Concerning judicial review of
    rates and classifications,
    [a]ny order or decision of the Commissioner . . . may be
    appealed to the North Carolina Court of Appeals by any
    party aggrieved thereby. Any such order shall be based on
    findings of fact, and if applicable, findings as to trends
    related to the matter under investigation, and conclusions
    of law based thereon. Any order or decision of the
    Commissioner, if supported by substantial evidence, shall
    be presumed to be correct and proper. . . .
    N.C. Gen. Stat. § 58-2-80 (2015). After an order or decision of the Commissioner is
    appealed to this Court,
    [s]o far as necessary to the decision and where presented,
    the court shall decide all relevant questions of law,
    interpret constitutional and statutory provisions, and
    determine the meaning and applicability of the terms of
    any action of the Commissioner. The court may affirm or
    reverse the decision of the Commissioner, declare the same
    null and void, or remand the case for further proceedings;
    or it may reverse or modify the decision if the substantial
    rights of the appellants have been prejudiced because the
    Commissioner's findings, inferences, conclusions or
    decisions are:
    (1) In violation of constitutional provisions, or
    -7-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    (2) In excess of statutory authority or jurisdiction of the
    Commissioner, or
    (3) Made upon unlawful proceedings, or
    (4) Affected by other errors of law, or
    (5) Unsupported by material and substantial evidence
    in view of the entire record as submitted, or
    (6) Arbitrary or capricious.
    N.C. Gen. Stat. § 58-2-90(b) (2015). This Court has further explained that,
    [w]hen reviewing an order by the Commission, this Court
    must examine the whole record and determine whether the
    Commissioner’s conclusions of law are supported by
    material and substantial evidence. The whole record test
    requires the reviewing court to consider the record
    evidence supporting the Commissioner’s order, to also
    consider the record evidence contradicting the
    Commissioner’s findings, and to determine if the
    Commissioner’s decision had a rational basis in the
    material and substantial evidence offered. Substantial
    evidence is such relevant evidence as a reasonable mind
    might accept as adequate to support a conclusion. It is
    more than a scintilla or a permissible inference.
    The Commissioner determines the weight and sufficiency
    of the evidence presented during the hearing, including the
    credibility of any witnesses. It is not our function to
    substitute our judgment for that of the Commissioner when
    the evidence is conflicting. Instead, the Commissioner’s
    order is presumed correct if it is supported by substantial
    evidence. The order must conform to the guidelines set out
    in [N.C. Gen. Stat.] § 58-36-10[.]
    ....
    As long as the Commissioner's order meets the criteria of
    [N.C. Gen. Stat.] § 58-36-10 and is supported by material
    -8-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    and substantial evidence, the order should be upheld.

    358 N.C. 539
    , 
    597 S.E.2d 128
    (2004). Relevant to this appeal, the following standards apply to
    the making and use of property insurance rates:
    (1) Rates or loss costs shall not be excessive, inadequate or
    unfairly discriminatory.
    (2) Due consideration shall be given to actual loss and
    expense experience within this State for the most recent
    three-year period for which that information is
    available; to prospective loss and expense experience
    within this State; to the hazards of conflagration and
    catastrophe; to a reasonable margin for underwriting
    profit and to contingencies; to dividends, savings, or
    unabsorbed premium deposits allowed or returned by
    insurers to their policyholders, members, or
    subscribers; to investment income earned or realized by
    insurers from their unearned premium, loss, and loss
    expense reserve funds generated from business within
    this State; to past and prospective expenses specially
    applicable to this State; and to all other relevant factors
    within this State: Provided, however, that countrywide
    expense and loss experience and other countrywide
    data may be considered only where credible North
    Carolina experience or data is not available.
    (3) In the case of property insurance rates under this
    Article, consideration may be given to the experience of
    property insurance business during the most recent
    five-year period for which that experience is
    available. . . .
    (4) Risks may be grouped by classifications and lines of
    -9-
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    insurance for establishment of rates, loss costs, and
    base premiums. Classification rates may be modified to
    produce rates for individual risks in accordance with
    rating plans that establish standards for measuring
    variations in hazards or expense provisions or both.
    Those standards may measure any differences among
    risks that can be demonstrated to have a probable effect
    upon losses or expenses. . . .
    ....
    (6) To ensure that policyholders in the beach and coastal
    areas of the North Carolina Insurance Underwriting
    Association whose risks are of the same class and
    essentially the same hazard are charged premiums that
    are commensurate with the risk of loss and premiums
    that are actuarially correct, the North Carolina Rate
    Bureau shall revise, monitor, and review the existing
    territorial boundaries used by the Bureau when
    appropriate to establish geographic territories in the
    beach and coastal areas of the Association for rating
    purposes. In revising these territories, the Bureau shall
    use statistical data sources available to define such
    territories to represent relative risk factors that are
    actuarially sound and not unfairly discriminatory. The
    new territories and any subsequent amendments
    proposed by the North Carolina Rate Bureau or
    Association shall be subject to the Commissioner's
    approval and shall appear on the Bureau's Web site, the
    Association's Web site, and the Department's Web site
    once approved.
    (7) Property insurance rates established under this Article
    may include a provision to reflect the cost of reinsurance
    to protect against catastrophic exposure within this
    State. Amounts to be paid to reinsurers, ceding
    commissions paid or to be paid to insurers by
    reinsurers, expected reinsurance recoveries, North
    Carolina exposure to catastrophic events relative to
    other states' exposure, and any other relevant
    - 10 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    information may be considered when determining the
    provision to reflect the cost of reinsurance.
    N.C. Gen. Stat. § 58-36-10 (2015).
    1.     Underwriting Profit
    In the Bureau’s first challenge to the Commissioner’s order, the Bureau claims
    the underwriting profit provision adopted by the Commissioner violates applicable
    legal and constitutional standards. We disagree.
    Our courts have long recognized the requirement that the Commissioner set
    rates to allow insurers to earn “a fair and reasonable profit” after the payment of
    losses and operating expenses. See In re N.C. Fire Ins. Rating Bureau, 
    275 N.C. 15
    ,
    34, 
    165 S.E.2d 207
    , 220 (1969) (“1967 Fire”) (explaining “that the premium [must] be
    fixed at a level which will enable the insuring company . . . (1) to pay the losses which
    will be incurred during the life of the policies to be issued under such rates, (2) to pay
    other operating expenses, and (3) to retain a ‘fair and reasonable profit’ and no more”).
    “An insurance company's total profit is derived from two distinct parts of the
    insurance business – (1) profit earned by the insurance operations and (2) profits
    earned by investing capital and surplus funds.” 2001 
    Auto, 160 N.C. App. at 421
    , 586
    S.E.2d at 473. Yet, in North Carolina, the total profit is not considered in determining
    whether rates allow insurers to earn a fair and reasonable profit; only the profit from
    the insurance operations is considered. See State ex rel. Comm’r of Ins. v. N.C. Rate
    Bureau, 
    300 N.C. 381
    , 444, 
    269 S.E.2d 547
    , 586 (1980) (“In determining whether an
    - 11 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    insurer has made a reasonable profit, the amount of business done rather than its
    capital should be considered, and profits should be determined by subtracting losses
    and expenses from the total of premiums actually received, to the exclusion of profit
    on capital and surplus, and excess commissions paid to agents but considering
    interest on unearned premiums and related elements.”) (emphasis in original)
    (quotation marks and citation omitted).
    The profit from insurance operations includes both the
    underwriting profit and investment income from
    policyholder-supplied funds. The underwriting profit can
    be defined as the difference between insurance premiums
    collected and the amount the company pays out for losses
    and expenses. Policyholder-supplied funds are the amount
    of premiums paid to the insurance company. Policyholder-
    supplied funds are usually invested during the insurance
    coverage period.
    2001 
    Auto, 160 N.C. App. at 421
    -22, 586 S.E.2d at 473. Although underwriting profit
    is a component of the profit earned by the insurance operations, which must be
    sufficient to allow insurers to earn fair and reasonable profit, there are no
    requirements specific to underwriting profit.            “[A] reasonable margin for
    underwriting profit and to contingencies[]” is, however, among the factors that “shall”
    be considered in the making and use of rates. N.C. Gen. Stat. § 58-36-10(2).
    In this case, the filing included an underwriting profit of 10.5% of premium.
    Upon review, the Commissioner rejected the Bureau’s underwriting profit provision
    in favor of an underwriting profit of 5.2% of premium. As stated above, the Bureau
    now claims this was error.
    - 12 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    The Bureau’s argument that the Commissioner’s underwriting profit provision
    violates legal and constitutional standards is founded on its assertion that a “fair and
    reasonable profit” must be equal to and determined using the cost of equity (also
    known as the “cost of capital” or the “cost of equity capital”). The Bureau claims the
    only evidence of the cost of equity in this case was in the prefiled testimony of James
    H. Vander Weide, a Bureau witness whom the parties stipulated was an expert in
    “economics and finance and profit as regards to the property/casualty insurance
    industry.” Vander Weide testified the cost of equity for the average company writing
    homeowners’ insurance in North Carolina is in the range of +9.1% to +12.8%.
    Therefore, the Bureau contends the Commissioner erred by rejecting the filed
    underwriting profit provision and by choosing an underwriting profit provision that
    did not produce a profit within the cost of equity range identified by Vander Weide.
    Upon review of the cases cited by the Bureau, we are not convinced the cost of
    equity is a constitutionally mandated standard, as the Bureau asserts. Thus, we
    affirm the Commissioner’s rejection of the filed underwriting profit provision.
    The Bureau argues North Carolina law has long defined a “fair and reasonable
    profit” as the level of profit demanded by the investment market on business ventures
    of comparable risk, which the Bureau equates to the cost of equity. The Bureau then
    relies on 1967 Fire and the older Fed. Power Comm’n v. Hope Natural Gas Co.,

    67 L. Ed. 1176
    (1923)
    (“Bluefield Waterworks”), cases to support its assertion that a cost of equity analysis
    is compelled by the United States Constitution. Upon review of 1967 Fire, we find no
    such requirement, nor mention, of the cost of equity. In that case, our Supreme Court
    explained that whether an amount is “a fair and reasonable profit, an excessive
    profit[,] or an insufficient profit must be determined by the Commissioner from
    evidence[, which] involves a projection into the future of past experience and present
    conditions.” 1967 
    Fire, 275 N.C. at 39
    , 165 S.E.2d at 224. The Court then stated, “[i]t
    involves consideration of profits accepted by the investment market as reasonable in
    business ventures of comparable risk.” 
    Id. The Court
    never mandated that a fair
    and reasonable profit be determined solely using a cost of equity analysis. Similarly,
    there is no mandate in Hope Natural Gas or Bluefield Waterworks.                   The
    Commissioner offered the following explanation for the absence of any references to
    the cost of equity in those decision:
    255. These two early U.S. Supreme Court cases indicate
    that the proper rate of return for regulated industries is a
    return commensurate with the returns that could be
    earned by industries of comparable risk.
    256. Both Vander Weide and Appel claim that Hope
    Natural Gas and Bluefield Waterworks require a cost of
    capital analysis. However, this cannot possibly be true
    because Hope Natural Gas was decided in 1944 and
    Bluefield Waterworks was decided in 1923. Vander Weide
    and Appel acknowledge that in the early days of regulation
    a comparable earning analysis, like the analyses proffered
    - 14 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    by Department witnesses Schwartz and O’Neil, was an
    accepted methodology until comparable earnings was
    abandoned in favor of market-based concepts like the cost
    of capital.     O’Neil notes that from 1921 through
    approximately the mid-1960’s, The 1921 NAIC Profit
    Formula, which allowed a pre-tax 5% of premium without
    consideration of investment income, was in use. That 5%
    of premium has also been mentioned in an older North
    Carolina case as an amount “generally approved in the
    industry.”

    [,] 315[,]

    utilized in regulatory matters when Hope Natural Gas and
    Bluefield Waterworks were decided.
    (Citations to transcripts and exhibits in the present case omitted; emphasis in
    original). We find the Commissioner’s analysis supported by the evidence and case
    law and hold it persuasive. Furthermore, our Supreme Court has acknowledged that,
    “[i]n North Carolina, there is no prescribed methodology for calculating the return on
    profits (profit methodology), and [it] has specifically recognized that creativity is
    acceptable within the parameters of the applicable statutes.” State ex rel. Comm’r of

    methodology and in adopting an underwriting profit provision that did not return a
    profit within the range identified by Vander Weide.
    The Bureau also challenges the legality of the profit methodology used by the
    Commissioner to reach his chosen underwriting profit provision. The Commissioner
    explained his selection of a comparable earnings profit methodology to determine the
    appropriate underwriting profit provision in findings 261 to 297. The Bureau claims
    the profit methodology used in the present case is erroneous as a matter of law
    because it is identical to the methodology rejected in 1996 Auto.
    In 1996 Auto, our Supreme Court reviewed this Court’s determination that the
    profit methodology used by the Commissioner in setting rates following the Bureau’s
    1996 auto filing was identical to the profit methodology previously rejected by this
    Court in 1994 Auto. 1996 
    Auto, 350 N.C. at 542-43
    , 516 S.E.2d at 152. For a complete
    understanding of our precedent, we briefly review those cases.
    In 1994 Auto, this Court remanded the Commissioner’s order for recalculation
    of the underwriting profit provision upon concluding the Commissioner erred as a
    matter of law in considering investment income from capital and surplus in his
    ratemaking 
    calculations. 124 N.C. App. at 684-86
    , 478 S.E.2d at 801-802. In that
    case, the error was evident because the Commissioner’s “formula included a line item
    and calculation for ‘Income from Capital and Surplus.’ ”

    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    In 1996 Auto, the Commissioner attempted to distinguish his profit
    methodology and ratemaking calculations following the Bureau’s 1996 auto filing
    from those rejected in 1994 
    Auto. 350 N.C. at 543
    , 516 S.E.2d at 152. The Court
    summarized the Commissioner’s calculations in 1994 Auto in its 1996 Auto decision
    as follows:
    he calculated the target total return of the insurance
    industry based on the total returns of industries of
    comparable risk. He then subtracted the investment
    income on capital and surplus from this total return and
    arrived at a total return on insurance operations.
    
    Id. The Court
    then explained the Commissioner’s calculations being challenged in
    1996 Auto as follows:
    the Commissioner began with a direct estimate and
    justification of the return on operations, rather than a total
    return, and derived his profit provisions from this
    estimated return on operations without explicitly including
    in his calculations investment income from capital or
    surplus. The Commissioner reasons that this method
    keeps the two calculations distinct, whereas the rejected
    method in the prior case combined the investment income
    from capital and surplus into the actual ratemaking
    calculation.
    
    Id. Upon review
    in 1996 Auto, this Court agreed with the Bureau’s argument that
    “the Commissioner simply ‘repackaged’ his calculations by starting with a return on
    operations as his target in order to avoid the appearance of explicitly considering
    investment income on capital and surplus, but in essence accomplished exactly what
    we have previously disallowed.” 
    129 N.C. App. 662
    , 666, 
    501 S.E.2d 681
    , 685 (1998).
    - 17 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    This was evident by the Commissioner’s admission that the “ ‘return on operations
    may be tested to ensure it will result in a “total return” commensurate with the “total
    return” of businesses of comparable risk by adding the income from capital and
    surplus to the return on operations.’ ” 
    Id. Thus, this
    Court, bound by 1994 Auto, held
    “the Commissioner improperly considered income from capital and surplus in
    arriving at his total return[.]” 
    Id. On further
    appeal to our Supreme Court based on
    a dissent from this Court’s majority decision, our Supreme Court 
    affirmed. 350 N.C. at 545
    , 516 S.E.2d at 153-54.
    As stated above, the Bureau now claims the profit methodology in the instant
    case is identical to the methodology rejected in 1996 Auto. In support of its argument
    the Bureau points to the following exchange during the testimony of Allan I.
    Schwartz, a Department witness whose underwriting profit provision the
    Commissioner adopted:
    Q.     Is it correct that your underwriting profit provision
    began with a direct estimate of a return on operations,
    rather than a total return, and you derive your
    underwriting profit provision from this estimated return
    on operations without explicitly including in your
    calculations investment income from capital and surplus?
    A.     Yes.
    Because Schwartz answered affirmatively in response to the question framed in the
    precise language used to describe the profit methodology rejected by both this Court
    and our Supreme Court in 1996 Auto, the Bureau claims we are bound by 1996 Auto.

    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    See In re Civil Penalty, 
    324 N.C. 373
    , 384, 
    379 S.E.2d 30
    , 36-37 (1989) (“Where a panel
    of the Court of Appeals has decided the same issue, albeit in a different case, a
    subsequent panel of the same court is bound by that precedent, unless it has been
    overturned by a higher court.”)
    Upon review of the Commissioner’s findings, we do not think the profit
    methodology used in the instant case was the same as that rejected in 1996 Auto.
    First, there is no indication that either Schwartz or the Commissioner tested their
    underwriting profit provisions by adding the profit earned from investing capital and
    surplus to the profit earned by the insurance operations to compare total returns, as
    was held to be error in 1996 Auto. Second, the Commissioner clearly indicates in the
    order that his profit methodology is in keeping with the Commissioner’s order
    following the Bureau’s 2001 auto filing, which this Court upheld in 2001 Auto.
    In 2001 Auto, this Court recognized that “[t]he disagreement between the
    Bureau and the Commissioner regarding the legal significance of the [1994 Auto and
    1996 Auto] appeals forms the basis of the current 
    appeal.” 160 N.C. App. at 419
    , 586
    S.E.2d at 472. This Court then reviewed those prior cases and addressed whether
    the Commissioner improperly considered investment income from capital and
    surplus funds while calculating the ordered insurance rates. 160 N.C. App. at 
    421, 586 S.E.2d at 473
    . This Court explained that in 1994 Auto and 1996 Auto, “the
    Commissioner defined ‘business ventures of comparable risk’ as the total profit of the
    - 19 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    insurance industry[]” and then, “[i]n order to set a rate equal to comparable
    businesses . . . , the Commissioner subtracted capital investment income and
    investment income from policyholder-supplied funds from total returns to reach the
    underwriting 
    profit[.]” 160 N.C. App. at 422
    , 586 S.E.2d at 474.        This Court
    distinguished the Commissioner’s ratemaking formula in 2001 Auto in that, “[r]ather
    than attempting to find a total return, the Commissioner set the return on insurance
    operations as his 
    target.” 160 N.C. App. at 423
    , 586 S.E.2d at 474. This Court then
    identified the pertinent findings by the Commissioner, in which the Commissioner
    rejected the Bureau’s cost of equity methodology on the basis that it considered the
    total return of businesses of comparable risk in violation of North Carolina law
    prohibiting consideration of investment on capital and surplus, and instead adopted
    the comparable earnings methodology of Department witness Schwartz, the same
    witness relied on by the Commissioner in the present case, on the basis that
    Schwartz’s profit methodology only took the profit from insurance operations into
    
    account. 160 N.C. App. at 423-26
    , 586 S.E.2d at 474-76. Upon review, this Court
    affirmed the Commissioner’s order because “the Commissioner focused on the return
    on insurance operations as the appropriate target for his 
    calculations.” 160 N.C. App. at 426
    , 586 S.E.2d at 476.
    In further support of our holding that the cost of equity is not mandated, this
    Court explained as follows:
    - 20 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    In addition, we find the Bureau's argument that the
    Commissioner must set his target as the total rate of return
    to be unpersuasive. No statute or any case has required
    the Commissioner to focus on the total rate of return for
    the insurance industry. Instead, previous appellate court
    opinions have declared that the return on operations is the
    only portion of income the Commissioner can consider
    during the ratemaking process. If the Commissioner had
    compared total returns here, as he did in previous
    ratemaking orders, the Commissioner would have been
    required to add capital and surplus funds somehow. By
    using insurance operations as the comparable industry, the
    Commissioner did not need to consider investment income
    on capital and surplus funds. Accordingly, the investment
    income on capital and surplus funds has not been used in
    the 2001 ratemaking calculation. The Commissioner's
    underwriting profit provision comports with the
    requirements of [N.C. Gen. Stat.] § 58-36-10 as well as the
    holdings of 1994 Auto and 1996 
    Auto. 160 N.C. App. at 426-27
    , 586 S.E.2d at 476.
    The comparable earnings profit methodology employed by the Commissioner
    in the present case appears the same as that which was upheld in 2001 Auto. And,
    in the present case, the Commissioner issued findings and conclusions, all of which
    are supported by evidence in the record, that are similar to those issued in 2001 Auto.
    Those findings and conclusions are to the effect that, first, the Bureau’s underwriting
    profit provision, which sets the target return equal to the cost of equity, violates this
    State’s prohibition on the consideration of investment income from capital and
    surplus in ratemaking and, second, the comparable earnings profit methodology used
    by the Department’s witnesses to determine an appropriate underwriting profit
    - 21 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    provision adheres to North Carolina’s legal requirements because it only takes into
    account the profit from the insurance operations.
    The Bureau acknowledges the Commissioner’s reliance on 2001 Auto, but
    dismisses that reliance as error on the basis that 2001 Auto is directly contrary to
    this Court’s decisions in 1994 Auto and 1996 Auto. Therefore, the Bureau contends
    we are bound by those earlier cases. See Graham v. Deutsche Bank Nat’l Trust Co.,
    __ N.C. App. __, __, 768 S.Ed.2d 614, 617 (2015) (“[W]here there is a conflicting line
    of cases, a panel of this Court should follow the older of those two lines.”) (quotation
    marks and citation omitted). It is clear, however, from this Court’s discussion in 2001
    Auto that the decisions are not contradictory.
    Because the Commissioner’s profit methodology in the present case is in accord
    with that upheld by this Court in 2001 Auto, we overrule the Bureau’s argument that
    the underwriting profit provision adopted by the Commissioner is legally erroneous.
    As an aside, we note the filed underwriting profit provision championed by the
    Bureau fails by their own calculations to meet the cost of equity that the Bureau
    claims is a minimum standard. The Bureau’s calculations show that the filed 10.5%
    of premium underwriting profit results in a post-tax total return from underwriting
    of 6.87% of premium. When the underwriting profit is considered with the net
    investment gain on insurance transactions, the Bureau’s calculations show post-tax
    total returns of 7.67% of premium and 7.06% of net worth, which the Bureau
    - 22 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    acknowledges is below the cost of equity. Thus, even if we were to accept the Bureau’s
    assertion that cost of equity is a mandatory requirement, the Bureau’s underwriting
    profit provision fails to meet that mandate.
    2.      Net Cost of Reinsurance
    The Bureau next argues the Commissioner erred in determining the net cost
    of reinsurance to be included in rates, which the Commissioner addressed in findings
    375 through 454.
    Reinsurance is insurance purchased by primary insurers from other insurance
    companies, or reinsurers, to mitigate the risk of large payouts in excess of what a
    primary insurer could bear in the event of catastrophic losses. It does so by spreading
    the risk between primary insurers and reinsurers. Reinsurers are willing to accept
    portions of the risk associated with potential catastrophic losses in exchange for a
    share of the premiums paid by the insureds. Primary insurers, in turn, pass the
    expense of reinsurance to the insureds by including the net cost of reinsurance in the
    rates. A large portion of the exposure to catastrophic losses in North Carolina is due
    to hurricanes.
    In this case, the Bureau’s filing included a provision for a net cost of
    reinsurance of 17.5% of premium. The Bureau based its provision on an analysis
    performed by David Appel, who was stipulated as an expert in “economics and finance
    and profit as regards the property/casualty insurance industry.” As he explained in
    - 23 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    his prefiled testimony, Appel “developed a procedure to include the ‘net cost of
    reinsurance’ as an expense in the direct homeowners rates in North Carolina.” Appel
    likened his “procedure” to what is used in Florida, “where insurers make rates using
    direct losses and expenses, but then add in a provision which covers the cost (to the
    primary insurer) of the reinsurer’s profit and expense.” Appel then explained his
    “procedure” in detail and expressed his beliefs that his calculations accurately
    reflected the net cost of reinsurance in North Carolina and that the net cost of
    reinsurance was appropriately included in homeowners’ insurances rates in North
    Carolina.
    The substance of Appel’s prefiled testimony as it relates to determining the net
    cost of reinsurance can be summarized as follows: Appel adopted the ratemaking
    assumption “that there is a single aggregate company that is the composite of all
    carriers in the state.”   Appel assumed the hypothetical company maintains a
    reinsurance program with specific provisions that Appel believed “reflect the types of
    reinsurance programs that insurers typically purchase to protect against the
    potentially catastrophic losses that are attendant to the hurricane risk to which the
    state is exposed.” Appel then used statewide aggregate loss distributions produced
    and provided by AIR Worldwide Corporation (“AIR”), a provider or risk modeling
    software and consulting services, which were based on AIR’s loss estimates from
    AIR’s warm sea surface temperature (“WSST”) model, as opposed to AIR’s standard
    - 24 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    (“STD”) model, and included the phenomenon of demand surge, to determine the
    amount of losses that would be subject to reinsurance coverage as a share of the total
    hurricane losses in the state. Based on the projected reinsured losses, Appel then
    developed a “competitive market” reinsurance premium. Appel testified that he
    calculated “the reinsurance premium is 23.9% of statewide direct premium, while the
    net cost of reinsurance is 17.5% of premium.”
    To counter Appel’s testimony, the Department cross-examined Appel and put
    on its own evidence tending to show that the Bureau’s net cost of reinsurance
    provision was overstated and not reflective of the reinsurance market in North
    Carolina. Department witnesses Schwartz and Mary Lou O’Neil, both of whom were
    stipulated as “expert property/casualty insurance actuaries[,]” and Evan D. Bennett,
    who the Bureau stipulated was an expert in reinsurance, expressed concern that the
    Bureau’s provision was based on a hypothetical model and no documentation or data
    was presented to support the assumptions and methodologies underlying the model
    or Appel’s calculations.
    Upon review of the evidence concerning net cost of reinsurance in this case, the
    Commissioner rejected the Bureau’s filed net cost of reinsurance of 17.5% of premium
    and ordered a net cost of reinsurance of 10% of premium. The Bureau now contends
    the Commissioner erred in doing so.
    - 25 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    At the outset, it is apparent from the Commissioner’s order that the
    Commissioner fully considered the evidence on the net cost of reinsurance, as the
    Commissioner summarized both the Bureau’s and the Department’s cases and
    explained his reasons for rejecting the Bureau’s filed net cost of reinsurance provision
    and adopting the 10% provision. Despite the Commissioner’s detailed order, the
    Bureau claims the Commissioner erred.
    The Bureau first challenges the Commissioner’s rejection of the filed net cost
    of reinsurance provision. The Bureau contends the filed net cost of reinsurance
    provision based on the “procedure” developed by Appel, which the Bureau now refers
    to as an “economic model,” was reasonable and supported by the evidence.
    The Commissioner’s rejection is concisely explained in the following findings:
    446. . . . Basically what the Commissioner was presented
    with in regards to the net cost of reinsurance was a
    hypothetical model, poorly documented, that was
    developed by an economist with no discernible background
    in reinsurance other than vague associations with other
    professionals who may have some reinsurance experience.
    Although market information was produced on rebuttal to
    support model input, the model does not reflect the
    significant price decreases in the market over the past
    couple of years because the model is not market-based.
    Moreover, the reinsurance model utilizes the AIR WSST
    model to estimate losses; however, the scientific
    underpinnings of the WSST are debatable and the WSST
    results in significantly higher losses than the STD model,
    which produced losses in this filing that the Commissioner
    has already found excessive.
    447.   Given all of the issues . . ., and the fact that the
    - 26 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    proposed net cost of reinsurance represents 22.1% of the
    base rate for Owners, the Commissioner can only conclude
    that the Bureau has not met its burden of proof with
    regards to the reinsurance component of the indicated
    rates. . . .
    ....
    453. Thus, based on the foregoing, the Commissioner
    finds that the Bureau’s proposed net cost of reinsurance is
    excessive and will result in excessive rates.
    Although the Bureau acknowledges that the Commissioner has discretion in
    weighing the evidence, the Bureau contends the Commissioner abused his discretion
    in this case by disregarding evidence – both Appel’s testimony and “real world”
    evidence that reinsurance costs actually incurred are consistent with the model
    results – that the Bureau claims supports its filed net cost of reinsurance provision.
    Regarding Appel’s testimony, the Bureau points to the Commissioner’s finding
    number 446 and contends the evidence does not support the finding that Appel “had
    no discernable background in reinsurance.” In support of its challenge, the Bureau
    highlights portions of Appel’s testimony at the hearing which it claims demonstrate
    that Appel possessed the necessary experience in reinsurance to offer testimony on
    the subject; namely, that Appel developed the reinsurance model that was first used
    in a 2002 rate filing and, since that time, has been involved in other rate cases, has
    given presentations and lectures on the model, has rendered opinions in rate cases in
    which the net cost of reinsurance was included, has served as an arbitrator in rate
    cases, and has worked with various insurance companies.             Because of these
    - 27 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    experiences, the Bureau claims “[t]he Commissioner’s disregard of Dr. Appel’s
    testimony and the Bureau’s reinsurance model is arbitrary and capricious and an
    abuse of discretion.”
    Upon review of the Commissioner’s findings and the evidence, we hold the
    Commissioner did not abuse his discretion. First, upon review of finding 446, we
    disagree with the Bureau’s characterization of the Commissioner’s finding. When the
    finding is read in its entirety, it is clear the Commissioner was critiquing Appel’s
    development of the reinsurance model. The evidence in the record supports the
    finding that Appel had no discernable background in reinsurance when he developed
    his reinsurance model, as all of the experiences highlighted by the Bureau appear to
    have occurred since the model was developed and first used in 2002. Appel’s prefiled
    testimony was that he has had the opportunity to become aware of property
    reinsurance programs over the past several years because a substantial amount of
    his consulting work over the last dozen to 15 years involved property insurance
    matters. Appel also indicated it did not appear he gave any presentations or lectures
    on reinsurance or property-related matters before 2003 and, when he began doing so,
    they concerned the development of his model.
    While it is clear Appel has increasingly gained experienced in reinsurance
    since the early 2000s, that experience does not refute the Commissioner’s finding that
    the “hypothetical model . . . was developed by an economist with no discernible
    - 28 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    background in reinsurance . . . .”     Nor does Appel’s subsequent experience in
    reinsurance show the Commissioner erred by placing greater weight on the testimony
    of the Department’s witnesses, one of which was an expert in reinsurance; especially
    where there was evidence that Appel lacked the experience to develop a reinsurance
    model, the model lacked documentation, and the hypothetical model did not reflect
    reinsurance in North Carolina.
    Regarding the “real world” evidence that the Bureau claims was improperly
    disregarded, the Bureau points to Exhibit RB-33, which was compiled by Appel and
    presented during the Bureau’s rebuttal case. Appel explained that RB-33 included
    the North Carolina Farm Bureau’s (“Farm Bureau”) insurance expenses for each of
    the years between 2001 and 2013 and showed the percent of Farm Bureau’s direct
    premium ceded to reinsurance.       Appel used Farm Bureau’s data to test the
    reasonableness of his reinsurance model and concluded that the filed net cost of
    reinsurance was well below that of Farm Bureau.
    The Commissioner addressed this “real world” evidence in finding 450 and
    determined its usefulness for comparison purposes was “nil” because the data
    included “quota share” reinsurance, or non-catastrophe reinsurance, in all but one of
    the years. The Bureau now contends the Commissioner’s disregard of the Farm
    Bureau data was in error because, although Appel acknowledged that, “[i]n some
    years, there’s quota share reinsurance in addition to catastrophe excess of loss
    - 29 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    reinsurance[]” and, therefore, the “percent ceded likely overstates to some extent the
    amount that is strictly catastrophe excess of loss[,]” Appel’s testimony was that in
    catastrophe prone areas such as North Carolina, “the quota share . . . is going to be
    priced much closer to catastrophe reinsurance than quota share would be in an
    environment which was not catastrophe prone because it bears a fair bit of the
    catastrophe exposure.” Thus, the Bureau claims Appel’s testimony shows the Farm
    Bureau data is relevant evidence of the cost of reinsurance in North Carolina.
    While the Commissioner may have understated the relevance of the Farm
    Bureau data by assigning it zero usefulness for comparison purposes, we are hesitant
    to say that the Commissioner erred in disregarding the data where, on appeal, the
    Bureau has failed to direct this Court to any concrete evidence indicating what
    portion of the Farm Bureau data was not reinsurance to guard against the risk of
    catastrophe losses. Moreover, as found by the Commissioner in finding 451 and
    argued by the Department on appeal, our Supreme Court has recognized that “the
    loss experience data of a single carrier in this State does not establish the ‘composite’
    of loss experience of all the carriers, which the establishment of the Bureau was
    intended to create.” Foremost Ins. Co., Inc. v. Ingram, 
    292 N.C. 244
    , 249, 
    232 S.E.2d 414
    , 418 (1977). This seems to hold particularly true where the single carrier, Farm
    Bureau in the present case, offers homeowners’ insurance extensively, but
    exclusively, in North Carolina. While the Bureau claims this makes Farm Bureau
    - 30 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    “uniquely reflective” of a single hypothetical company operating in North Carolina,
    both Bureau and Department witnesses acknowledged that many insurers in North
    Carolina are multi-state and multi-line carriers.        Department witness Schwartz
    explained that he did not believe the Bureau’s calculation took into account that “the
    aggregate company in North Carolina . . . writes other lines of insurance in North
    Carolina, and writes business in other states, and has a substantial premium base
    and surplus amount which would allow for a higher retention.”           Based on this
    evidence, we cannot hold the Commissioner abused his discretion in disregarding the
    Farm Bureau data as illustrative of reinsurance for the entire state.
    In addition to arguing the Commissioner erred in rejecting its filed net cost of
    reinsurance provision, the Bureau also argues the Commissioner erred in selecting a
    10% net cost of reinsurance provision. The Bureau claims the selected provision is
    unsupported by material and substantial evidence.
    The Commissioner’s adoption of the 10% net cost of reinsurance is best
    explained in the following findings:
    447. . . . Schwartz recommended that, in light of the
    Bureau’s failure to support its net cost of reinsurance
    provision, it would be appropriate to use a net cost of
    reinsurance of $0 (zero). The Commissioner does agree
    that $0 might be appropriate, however, North Carolina is
    exposed to hurricanes and, without a doubt, insurers have
    sought to protect themselves from hurricane claims in
    North Carolina by purchasing reinsurance, a fiscally
    prudent decision and sound business practice. Thus the
    Commissioner considers it reasonable to include some
    - 31 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    factor above $0 in the rate for the net cost of reinsurance.
    ....
    448. Schwartz has proposed a factor of 10% of premium,
    based upon an analysis of historical countrywide data of
    the entire homeowners insurance industry over the last 28
    years. . . .
    449. Schwartz . . . testified that pursuant to [N.C. Gen.
    Stat.] § 58-36-10(2) countrywide data may be used where
    North Carolina experience is unavailable. . . .
    ....
    452. Schwartz provides a reasonable measure to set the
    net cost of reinsurance at 10% of premium given that we do
    not have actual composite North Carolina data available,
    and that the countrywide data . . . provides a reasonable
    benchmark to North Carolina because of similar measures
    of risk. . . .
    ....
    454. The Commissioner, taking into account the above
    and the undisputed fact that North Carolina is a coastal
    state prone (like its sister states in the southeastern
    United States) to hurricanes and tropical storms, finds that
    a net cost of reinsurance of 10% of premium is reasonable
    and will result in rates that are not excessive or
    inadequate.
    The Bureau now contends the Commissioner erred in the above findings
    because Schwartz was not an expert on reinsurance and, therefore, not competent to
    provide testimony on the subject. The Bureau also contends the Commissioner erred
    in relying on countrywide reinsurance data.
    - 32 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    Regarding the testimony by Schwartz, the Bureau claims that Schwartz did
    not meet the requirements of Rule 702(a) of the North Carolina Rules of Evidence
    and Daubert for admissibility of expert testimony. See N.C. Gen. Stat. § 8C-1, Rule
    702(a); Daubert v. Merrell Dow Pharms., Inc., 
    509 U.S. 579
    , 
    125 L. Ed. 2d 469
    (1993).
    Specifically, the Bureau contends that because Schwartz testified that he has never
    been engaged on a professional basis by a reinsurer, reinsurance broker, or primary
    insurer to price a reinsurance policy, has not individually been involved in a
    transaction for the purchase of reinsurance, and has never in a professional capacity
    recommended or calculated hurricane average annual losses for use by a reinsurer or
    reinsurance broker, Schwartz “lacks the ‘knowledge, skill, experience, training or
    education’ in the field of reinsurance to be competent to testify on the cost of
    reinsurance . . . .” We disagree.
    The Bureau ignores that Schwartz, an actuarial consultant, received the
    professional designation of Associate in Reinsurance from the Insurance Institute of
    America in 1998 (received the Reinsurance Association of America Award for
    Academic Excellence) after completing qualifying examinations and has been
    involved in numerous insurance rate cases in various states in recent years.
    Although Schwartz may not have been qualified to develop a reinsurance model,
    there is a significant difference between developing a model to project reinsurance
    costs and comparing modeled results to actual reinsurance data. Based on Schwartz’s
    - 33 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    reinsurance designation and experience as an actuary having participated in
    numerous rate cases, we hold Schwartz was competent to testify on the subject of
    reinsurance and the Commissioner did not abuse his discretion in considering or
    giving weight to Schwartz’s testimony.
    Regarding the Commissioner’s consideration of the countrywide reinsurance
    data presented by Schwartz and included in Schwartz’s prefiled testimony, the
    Bureau asserts the Commissioner’s reliance on the data was error because the data
    does not reflect the hurricane risks in North Carolina and the costs that insurers will
    incur to purchase reinsurance in North Carolina. The Bureau specifically points to
    Schwartz’s testimony and claims Schwartz acknowledged the data did not reflect
    catastrophe risks in North Carolina.
    A review of the portion of Schwartz’s testimony identified by the Bureau shows
    that Schwartz never acknowledged that the data was not reflective of North Carolina,
    but that the data is not that of North Carolina. To be exact, in response to the
    question, “Now, is it correct, Mr. Schwartz, that you cannot tell from the data . . .
    what the net cost of reinsurance is for catastrophe reinsurance in a state like North
    Carolina?”    Schwartz responded, “Yeah[, the data] doesn’t give catastrophe
    reinsurance data for North Carolina.” We think testimony that data is not for North
    Carolina and testimony that data is not reflective of North Carolina are very different
    responses. Moreover, Schwartz went on to testify that he was “not aware of where to
    - 34 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    obtain [catastrophe reinsurance data for North Carolina].” Schwartz stated that he
    believed the Department requested such information from the Bureau for use in
    analyzing the filing, but the Bureau indicated they did not have such information. In
    setting forth the standards and factors in the making and use of rates, N.C. Gen. Stat.
    § 58-36-10(2) provides that “countrywide expense and loss experience and other
    countrywide data may be considered only where credible North Carolina experience
    or data is not available.”     N.C. Gen. Stat. § 58-36-10(2).        As found by the
    Commissioner in finding 449, Schwartz acknowledged N.C. Gen. Stat. § 58-36-10(2).
    Finding 449, together with the Commissioner’s finding that “it is not appropriate to
    set a provision for net cost of reinsurance . . . based upon data presented for only one
    company[]” in finding 451, supports the Commissioner’s consideration of countrywide
    data. Thus, the Commissioner did not err.
    Even if the countrywide data was properly considered, the Bureau contends
    the Commissioner acted arbitrarily in selecting the 10% net cost of reinsurance
    provision from the data. Again, we disagree.          While 10% may not be an exact
    calculation, Schwartz’s recommendation and the Commissioner’s selection of 10% for
    the net cost of reinsurance was based on a reasoned analysis with a rational basis in
    the evidence. Specifically, the data relied on by Schwartz shows that, for the years
    included, the net cost of reinsurance as a percent of direct earned premium ranges
    from an average of 4.6% on a calendar year basis to a maximum of 10.1% on a
    - 35 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    calendar year basis, and from an average of 7.8% on an accident year basis and to a
    maximum of 15.9% on an accident year basis. Schwartz used that data to recommend
    a range of 5% to 16%, considering both the accident year and calendar year bases.
    Schwartz then selected a 10% net cost of reinsurance from the middle of the range.
    Upon review, it is clear that Schwartz’s analysis was well reasoned and constitutes
    material and substantial evidence. Furthermore, it supports the Commissioner’s
    findings and conclusions. Thus, the Commissioner’s selection of the 10% net cost of
    reinsurance was not arbitrary.
    The Bureau looks to the same countrywide data and references numbers from
    the column providing the percent of “ceded/direct earned premium” and points out
    that the average and maximum on an accident year basis are higher than the
    percentages used by Schwartz – respectively 9.7% and 22.5%. The Bureau then
    asserts that Schwartz and the Bureau arbitrarily picked the lower percentages for
    net cost of reinsurance. To support its assertion, the Bureau contends that when
    Schwartz was asked on cross-examination which was the appropriate number for the
    Commissioner to use, Schwartz testified that “both provide information[]” and did not
    explain why he choose 10%. Upon review of both the countrywide data used by
    Schwartz and the testimony of Schwartz cited by the Bureau, it is clear the Bureau
    misconstrues the data and Schwartz’s testimony. First, the percentages referenced
    by the Bureau are the result of a different calculation, “ceded/direct earned premium,”
    - 36 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    than the net cost of reinsurance as a percent of direct earned premium relied on in
    Schwartz’s analysis. Second, the portion of Schwartz’s testimony cited by the Bureau
    was not in reference to the difference between the figures identified by the Bureau
    and the figures relied on by Schwartz. Schwartz’s testimony was in reference to the
    inclusion of net cost of reinsurance analysis on both an accident year basis and a
    calendar year basis. Schwartz explained the difference between the two bases and
    stated they provide different information. In determining the range for net cost of
    reinsurance, Schwartz considered both bases.
    3.     Modeled Hurricane Losses
    In the third issue raised on appeal, the Bureau argues the Commissioner erred
    in reducing the modeled hurricane losses in the filing. The Commissioner addressed
    the modeled hurricane losses in findings 153 through 225.
    The Bureaus’ filed rates were based, in part, on long-term average annual
    hurricane losses of $316.1 million. These hurricane losses included in the Bureau’s
    filing were based on a report that was provided to the Bureau by AIR and entered
    into evidence as Exhibit RB-6A. The report includes an analysis of prospective
    hurricane losses based on AIR’s STD model, which incorporates AIR’s standard view
    of hurricane risk. In prefiled testimony, Bureau witness Robert Newbold, an expert
    in catastrophe modeling and Senior Vice President of AIR, explained that for the
    analysis requested by the Bureau, AIR ran 100,000 simulations or iterations of what
    - 37 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    could happen in the following year in order to derive average loss costs. Although
    Newbold admitted that, “[a]s with all models, [the] representation are not exact,”
    Newbold opined that “simulation methodology is the best available technique for
    estimating potential hurricane losses . . . .” Bureau witness Robert J. Curry, an
    expert property/casualty actuary who is responsible for managing and overseeing the
    operations of the Personal Property Actuarial Division of Insurance Services Office
    (“ISO”), echoed Newbold’s opinion and explained that using a simulated model to
    determine long-term average losses is a more accurate way of including the exposure
    than using actual hurricane losses.
    In the order, the Commissioner accepted the use of simulation modeling,
    explaining in finding 153 that “[t]he purpose in utilizing . . . the hurricane loss model
    is to avoid inordinate shifts, both upward and downward, in indicated rate levels
    which would result from reflecting large hurricane and other wind loss events only in
    the year in which they occur.” The Commissioner, however, refused to blindly accept
    the modeled hurricane losses included in the Bureau’s filing and considered the
    testimony of Bureau and Department witnesses to determine the credibility of the
    model. Based on the evidence presented, the Commissioner found it necessary to
    reduce the modeled hurricane losses, finding as follows:
    223. . . . The model provides useful information and
    certainly should be considered. However, models aren’t
    perfect; the problems and uncertainties of the model should
    be considered as well. The Commissioner finds herein that
    - 38 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    it is both necessary and appropriate to reduce the Bureau’s
    value for the modeled hurricane loss costs to a level that
    recognizes the bias and inherent uncertainty in modeling
    in general and catastrophe modeling, specifically.
    224. . . . The Commissioner finds that the average annual
    modeled hurricane losses of $316.1 million used in support
    of the filed rates is excessive based on the evidence. He
    finds that a reduction in the modeled hurricane losses of
    13.9% to 272.3 million is supported in the evidence.
    225. Thus, the Commissioner finds herein that the
    modeled hurricane losses utilized in the Bureau’s indicated
    rate calculation are excessive and will result in excessive
    rates. The +13.9% reduction in hurricane losses . . . will
    result in rates that are neither excessive nor inadequate.
    The Bureau now claims the Commissioner’s reduction of the modeled hurricane losses
    was arbitrary and capricious for several reasons.
    First, the Bureau contends the Commissioner erred in reducing the modeled
    hurricane losses because there is no evidence that uncertainty in the model results
    in an overstatement of the losses. The Bureau claims the Commissioner “effectively
    assumed that ‘uncertainty’ in modeling equates to ‘excessive losses[]’ ” without
    material and substantial evidence and contrary to the Commissioner’s findings
    regarding the validity of the model. We disagree that the Commissioner made such
    an unfounded assumption.
    While the Bureau is accurate in stating the Commissioner issued findings on
    the general acceptance of simulation modeling within the insurance industry to
    predict hurricane losses and noted verification procedures used to ensure that AIR’s
    - 39 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    models are as up-to-date and accurate as possible, it is clear from the evidence of both
    the Bureau and the Department that modeling is not infallible.             In fact, the
    Commissioner issued findings identifying specific testimony that modeling was not
    precise, had limitations, and that “glitches” had been discovered in the past. The
    Commissioner also devoted entire subsections of findings to the credibility of AIR’s
    models and both the Bureau’s and the Department’s cases, in which the
    Commissioner identified biases on all sides.         The Bureau does not attack any
    particular finding and, upon review of the record, the findings appear to be supported
    by the record evidence. Because of the admitted uncertainty in modeling, it was not
    inconsistent for the Commissioner to scrutinize the modeled losses despite his
    recognition that AIR’s models are widely used and accepted.
    Moreover, the Commissioner’s reduction of the modeled hurricane losses was
    not based on an unfounded assumption, it was based on the evidence, or the lack
    thereof, in the record. While the Bureau is correct in asserting that any uncertainty
    in the STD model may result in the understatement of losses as opposed to an
    overstatement of losses, the Bureau has not directed this Court to any evidence in
    the record that the modeled hurricane losses were understated; nor have we been
    able to find such evidence. Based on the evidence of record, it was well within the
    Commissioner’s discretion to weigh the competent evidence in the record and make
    adjustments as he deemed necessary.
    - 40 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    The Bureau, however, also takes issue with the evidence considered by the
    Commissioner in reducing the modeled hurricane losses. Specifically, the Bureau
    contends the Commissioner erred in relying on the testimony of O’Neil and Schwartz.
    The Bureau also contends the Commissioner erred in using benchmarks that are not
    based on material and substantial evidence.          We are not convinced that the
    Commissioner erred in either respect. Nevertheless, it is important to note that,
    while the Commissioner did rely on the testimony of O’Neil and Schwartz and the
    benchmarks as evidence that the modeled hurricane losses included in the filing were
    overstated, “the Commissioner [did] not rely[] upon the specific numerical values of
    their calculations to set a rate[,]” as the Commissioner explained in finding 215.
    The Bureau first contends the Commissioner erred in relying on testimony by
    O’Neil and Schwartz because they were neither offered nor qualified by knowledge,
    skill, experience, training, or education as experts in hurricane modeling. See N.C.
    Gen. Stat. § 8C-1, Rule 702(a); 
    Daubert, 509 U.S. at 588
    , 125 L. Ed. 2d at 480. In
    support of its argument, the Bureau directs this Court’s attention to finding 218a, in
    which the Commissioner found that “neither he nor any of the consultants hired by
    the Department nor anyone on his staff has the expertise to evaluate the inner
    workings of the model.” While we acknowledge the Commissioner’s finding, we are
    not convinced the finding supports the Bureau’s argument. A review of finding 218a
    and the subsequent findings indicate the Commissioner was not commenting on the
    - 41 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    qualifications of O’Neil and Schwartz to provide testimony regarding the results of
    AIR’s STD model, but regarding the “inner workings of the model[,]” to which neither
    O’Neil nor Schwartz offered testimony.      The Commissioner’s subsequent finding
    describing the type of review he was required to undertake because he lacked the
    expertise to analyze the inner-workings of the model adds perspective to finding 218a.
    The Commissioner explained that review as follows:
    218b. The Commissioner instead must rely on benchmarks
    that are offered in sworn evidentiary testimony. These
    benchmarks can be against results from other models, or
    against actual history. Each of the various benchmarks in
    the record has different evidentiary force that must be
    weighed.
    O’Neil and Schwartz, both of whom were stipulated as expert property/casualty
    insurance actuaries, were certainly qualified by knowledge, skill, and experience to
    review the results of the STD model and compare those results to the results of other
    models or historical losses. Thus, the Commissioner did not err in relying on their
    testimony.
    The Bureau next takes issue with the Commissioner’s use of “benchmarks” to
    validate the STD model. The Commissioner recognized four benchmarks which he
    used to estimate that modeled hurricane losses should be 13.1% to 21.5% lower than
    filed. The Bureau contends three of those benchmarks are not supported by material
    and substantial evidence in the record and, therefore, the Commissioner’s reliance
    thereon was arbitrary and capricious.
    - 42 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    At the outset, we re-emphasize that the Commissioner specifically noted the
    actual reduction of the modeled hurricane losses was not based on the benchmarks.
    In the first challenged benchmark, which the Commissioner explained in
    finding 218c, the Commissioner compared actual hurricane losses to modeled
    hurricane losses. That comparison was based off of AIR’s own validation in Exhibit
    RB-6C, which used bar graphs to compare observed and modeled losses for seventeen
    hurricanes dating back to 1989. Because AIR was comparing observed losses from
    past years to current model losses, AIR adjusted the actual losses by a 7% annual
    trend factor to account for inflation and exposure growth. The Commissioner noted
    in finding 218c that the adjusted actual losses for hurricanes Hugo, Fran, and Isabel,
    three hurricanes that caused significant losses in North Carolina, are 7.9% higher
    that the modeled hurricane losses. The Commissioner, however, also tested a 5%
    annual trend factor and found the adjusted actual losses are 21% lower than the
    modeled hurricane losses when the 5% factor is used. The Commissioner then found
    in finding 218c that an annual trend factor of below 5% is shown from inflation and
    home price indices, which the Commissioner acknowledged were not discussed at the
    hearing.
    The Bureau now contends the Commissioner’s analysis using the 5% annual
    trend factor was in error because the 5% factor was not based on evidence in the
    record and because the 5% factor does not include the exposure growth component to
    - 43 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    AIR’s validation. The Bureau claims the Commissioner picked the 5% factor because
    AIR’s validation did not support his desired reduction of the modeled hurricane losses
    and, therefore, the Commissioner “rewrote the evidence to generate another
    ‘benchmark’ in his result-oriented effort to reduce modeled losses and ensure that
    there would be no rate increase.” The Bureau is correct that the Commissioner’s use
    of the 5% annual trend factor and the Commissioner’s assertion that the annual trend
    factor is less than 5% are not based on evidence in the record. Thus, the portion of
    finding 218c indicating an annual trend factor between 3.5% and 4% is proper is error.
    We hold it was not error, however, for the Commissioner to test the 5% factor.
    In response to the Bureau, the Commissioner contends the 5% annual trend
    factor was just a number selected by the Commissioner to test the sensitivity of AIR’s
    7% factor. Assuming that was the purpose of the Commissioner’s calculations, it was
    useful and relevant for determining the sensitivity of the STD model. But even if
    that was not the intended purpose of testing the 5% factor, the Commissioner’s
    analysis and the portion of finding 218c that the annual trend factor was below 5%
    were harmless because the Commissioner’s ultimate reduction of the modeled
    hurricane losses was not based on the 5% factor.
    The second challenged benchmark, described by the Commissioner in finding
    218e, was based on the testimony of Department witness O’Neil. For the “O’Neil
    benchmark,” O’Neil conducted a comparison of modeled hurricane losses of AIR and
    - 44 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    Risk Management Solutions (RMS), a competitor of AIR. O’Neil’s comparison was of
    the WSST modeled hurricane losses of “Beach Plan”2 properties that had been
    projected for reinsurance purposes. O’Neil found that AIR projected losses of $247.4
    million and RMS projected losses of $141.0 million. O’Neil then determined that
    AIR’s modeled losses were roughly 27.4% higher than the average of the two models.
    Based on O’Neil’s testimony, the Commissioner found modeled hurricane losses could
    be 21.5% lower than filed. In rebuttal, Bureau witness Newbold took exception to
    usefulness of O’Neil’s comparison, but offered the results if the STD versions of AIR’s
    and RMS’s models were considered. Newbold testified that using STD versions of
    their respective models, AIR projected losses of $226.8 million and RMS projected
    losses of $167.5 million; thus, AIR’s modeled losses were roughly 14% higher than the
    average of the two models. Based on Newbold’s testimony, the Commissioner found
    modeled hurricane losses could be 13.1% lower than filed.
    The Bureau now contends O’Neil’s analysis was not material and substantial
    evidence because the models she compared were different from the model used in the
    filing and because the comparison was based only on the Beach Plan’s exposure,
    which makes up only a small portion of the entire state. Although the modeled
    hurricane losses compared by O’Neil were projected using WSST versions of AIR’s
    2 The Beach Plan is a residual market created by the legislature to provide insurance to
    homeowners in beach and coastal counties at a surcharge because insurers are not willing to write
    insurance policies.
    - 45 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    and RMS’s models and, therefore, different from the models used to project modeled
    hurricane losses in the filing, Newbold’s testimony regarding the results of the STD
    versions of the models adds credence to O’Neil’s testimony that AIR’s estimates were
    significantly higher than the estimates of RMS. Although such comparison may not
    be relevant to the actual reduction of the modeled hurricane losses, it is relevant to
    show that other models produce more modest loss projections. Additionally, although
    the Beach Plan only includes those territories nearest the coast and is not
    representative of the entire state, the evidence from AIR was that those coastal
    territories in the Beach Plan are most vulnerable to hurricane losses and account for
    much higher shares of the loss than exposure. Thus, we do not entirely dismiss the
    consideration of the Beach Plan modeled losses. Lastly, and most importantly, while
    the Commissioner may have used the benchmark to set the outer bounds for a
    reduction of the modeled hurricane losses, the benchmark was not used by the
    Commissioner to calculate his reduction of the modeled hurricane losses.
    The third benchmark challenged by the Bureau was based on the testimony of
    Department witness Schwartz.       The Commissioner described his review of the
    “Schwartz benchmark” in finding 218f. The Schwartz benchmark was based on a
    comparison of modeled hurricane losses and actual hurricane losses from filings
    dating back to 1998. Schwartz’s analysis showed that from 1992 to 2011 the ratio of
    actual to modeled hurricane losses was 53%. In finding 211, the Commissioner found
    - 46 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    that “Schwartz corrected for his perceived problems with the AIR model by
    judgmentally reducing the value of the projected losses in the filing by +10%.”
    The Bureau contends the Schwartz benchmark is not material and substantial
    evidence. While we agree that Schwartz’s 10% reduction in the modeled losses is not
    material and substantial evidence, the Schwartz analysis is relevant, material, and
    substantial evidence to show the comparison between observed losses and modeled
    losses for purposes of demonstrating AIR’s STD model overstated modeled hurricane
    losses in the recent past.
    The Bureau’s arguments against each of these benchmarks is that they are not
    material and substantial evidence. We disagree and hold the benchmarks were
    material and substantial evidence of the purpose for which they were recognized – to
    show that AIR’s modeled hurricane losses were not exact and were overestimated.
    While the Commissioner may have considered the benchmarks for determining
    the modeled losses were not entirely reliable, the Commissioner indicated his
    eventual reduction of the modeled hurricane losses was not based on the benchmarks.
    In fact, the Commissioner noted deficiencies in the benchmarks by stating in finding
    218g that “none of [the four benchmarks] on its own is completely reliable.” The
    Commissioner also recognized in finding 215 that O’Neil’s and Schwartz’s testimony
    may have contained some documentation issues and unsupported assumptions, but
    as we recognized above, the Commissioner overlooked those deficiencies because he
    - 47 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    was “not relying upon the specific numerical values of their calculations to set a rate.”
    The Commissioner correctly recognized in finding 215 that his duty was to determine
    “whether the Bureau met its burden of proof for this filing.” The Commissioner
    ultimately determined the Bureau failed to meet its burden of proof regarding three
    components of the modeled hurricane losses and determined it was proper to exclude
    those components from consideration, thereby reducing the modeled hurricane losses
    to be used in ratemaking. The Commissioner described his reduction as follows:
    218i. The Commissioner finds it helpful to tabulate the
    STD model output in the following format. From here, it
    can be seen that eliminating three sources of losses that
    were disputed by the Department witnesses: 1) the
    demand surge component ($17.0 million), 2) the losses
    arising from modeled CAT 5 events in North Carolina
    ($14.0 million), and 3) the losses ($12.8 million) arising
    from modeled hurricanes that make landfall somewhere
    other than the Carolinas, but which are presumed by the
    AIR model to continue into North Carolina with wind
    speeds below hurricane force, one would end up with an
    indicated average annual loss due to hurricanes of $272.3
    million, which is 13.9% below the filed amount, and within
    the range cited above. . . .
    The Bureau’s last argument regarding the Commissioner’s review of the
    modeled hurricane losses is that the Commissioner’s 13.9% reduction removes losses
    that insurers are required to pay. The Bureau contends the removal of the three
    components was arbitrary and suggests that the only reason for their removal is
    because the combined effect caused the modeled hurricane losses to fall within the
    range of the benchmarks.       We disagree with the Bureau’s assertion that the
    - 48 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    Commissioner’s decisions to exclude CAT 5 hurricanes, demand surge, and losses
    incurred from winds below 74 miles per hour were arbitrary and capricious.
    Concerning CAT 5 hurricanes, the Bureau asserts that the decision to remove
    the CAT 5 hurricanes from the modeled losses was arbitrary because the evidence
    was undisputed that it was statistically and meteorologically possible that a CAT 5
    hurricane could impact North Carolina. Although the Bureau recognizes that there
    has never been a CAT 5 hurricane impact in North Carolina in the period of time for
    which consistent historical data has been collected, the Bureau’s model hurricane
    losses include the admittedly extremely low probability events. In response, the
    Commissioner points to testimony from Newbold that there is less than a .1%
    probability a CAT 5 hurricane will strike North Carolina and indicating it is a very
    unlikely event. The Commissioner further points to prefiled testimony of Schwartz
    explaining that “[p]rojected hurricane events from the AIR model that have a
    probability of 0.1% or less . . . comprise about 7.7% of the overall projected modeled
    hurricane losses[,]” “projected hurricane events from the AIR model that have a
    probability of 0.5% or less . . . comprise about 22.7% of the overall projected modeled
    hurricane losses[,]” and “[m]ore than ½ of all the projected hurricane losses from the
    AIR model come from hurricane events that have a probability of 2.5% or less . . . .”
    After noting Schwartz’s testimony, the Commissioner found in finding 209 that
    “[w]hile the very low probability events have a large impact on projected losses, these
    - 49 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    very low probability events have the most uncertainty about whether the results are
    accurate.” In finding 193, the Commissioner also recalled O’Neil’s testimony that
    “[al]though . . . Newbold may be correct from a technical modeling viewpoint that a
    Category 5 storm is possible, it does not follow that it is appropriate to generate losses
    from such an event for inclusion in North Carolina Homeowners’ rates. Homeowners
    should not be required to pay for losses from a hypothetical event which has no basis
    in actual historical observation.” We hold the Commissioner’s findings concerning
    CAT 5 hurricanes are supported by the evidence and demonstrate a reasoned decision
    to exclude the losses from those storms due to the very low probability and high
    comparative costs included in the modeled hurricane losses.
    Concerning demand surge, the Commissioner recognized in finding 185 that
    “[d]emand surge accounts for the sudden and usually temporary increase in the cost
    of material, services, and labor due to increased demand following a catastrophe.”
    The Commissioner further noted in a footnote to that finding that, “[d]emand surge,
    at best, is a function of supply and demand . . . [and] at worst, is a function of price
    gouging.” The Commissioner then found in finding 187 that “[t]he analysis showed
    that there is an increase of 5.7% in gross losses when demand surge is applied.” In
    summarizing the testimony of O’Neil, the Commissioner indicated that O’Neil took
    issue with the inclusion of demand surge because the validation for demand surge
    was based on other states and there had not been an analysis for North Carolina
    - 50 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    events. O’Neil also contemplated that the North Carolina price gouging statute could
    limit demand surge. We find it significant that the Commissioner did not completely
    reject the possibility of demand surge, but instead disagreed with the Bureau’s
    analysis as follows:
    198a. The Commissioner agrees with O’Neil that the
    Demand Surge surcharge averaging 5.7% is not adequately
    supported by the Rate Bureau. He was able to review the
    demand surge impact on each of the 57,754 modeled losses.
    The Commissioner was surprised to find that nearly 40%
    of the modeled losses included additional losses due to
    demand surge. He finds that modeled events with loss
    amounts as low as $6 statewide loss included demand
    surge.
    198b. The Commissioner finds that nearly half of the total
    demand surge dollars . . . arise from modeled events that
    make landfall in states other than North Carolina.
    Presumably the North Carolina portion of losses excluding
    demand surge from events that make landfall elsewhere
    are only a fraction of the total, and yet, the formula
    provides the same percentage load in each state’s losses. It
    is not clear to the Commissioner why a major event in
    Florida that tracks into North Carolina doing relatively
    minor damage there should entail supply and demand
    problems in North Carolina.
    198c. Whatever study was done to develop the model, no
    details other than a table of factors were presented into
    evidence by the Rate Bureau.
    198d. AIR testified that it commonly runs the model either
    with or without demand surge, implying that it is not
    regarded by its end users as a necessary component of the
    model.
    - 51 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    It is clear from these findings that the Commissioner’s exclusion of demand surge
    was a result of the Bureau’s failure to meet its burden of proof. We hold these findings
    are supported by the evidence and demonstrate a coherent analysis by the
    Commissioner.
    Concerning losses from winds below 74 miles per hour, the Bureau contends
    the exclusion of those losses from modeled hurricane losses is arbitrary because “[t]he
    actual hurricane losses removed from the ratemaking data to prevent any duplication
    include all losses caused by winds of 40 mph or higher.” We are not convinced. It is
    undisputed that hurricanes are classified as storms with sustained winds at least 74
    miles per hour. As a result, O’Neil testified that “[she] didn’t think it appropriate to
    consider [losses caused by winds below 74 miles per hour] as hurricane losses in the
    model.” The Commissioner reflected O’Neil’s opinion in his findings and adopted it,
    resulting in the exclusion of losses incurred from non-hurricane force winds from
    modeled hurricane losses. While there may be reasons for the inclusion of such winds,
    the Commissioner’s determination is rationally based on the evidence presented and,
    therefore, was not arbitrary.
    Upon full review of the Commissioner’s analysis of the modeled hurricane
    losses, the Order shows the Commissioner performed a careful review of the evidence
    and did not arbitrarily reduce the modeled hurricane losses to be used in ratemaking.
    - 52 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    The Commissioner removed those sources of the modeled hurricane losses that he
    determined were questionable and not fully supported by the Bureau.
    4.     Allocation to Zones
    Lastly, the Bureau argues the Commissioner erred in rejecting its filed
    allocation of the net cost of reinsurance and underwriting profit to zones.         The
    Commissioner addressed the Bureau’s allocation in findings 455 to 469.
    The Bureau’s filed allocation was based on a simulation model developed by
    Bureau witness Appel. Appel explained that he used his model to calculate the risks
    faced by different regions in North Carolina and, instead of using the revised
    territories in the filing, allocated the net cost of reinsurance and underwriting profit
    between four zones: beach, coast, central, and mountains. The Bureau now claims
    the filed allocation “did not change the overall filed rate level; it simply accomplished
    the fundamental goal of allocating the reinsurance costs across the state proportional
    to the risk and thereby collecting a greater portion of the premium from the exposures
    which present a correspondingly greater risk.”
    The Commissioner took exception to the Bureau’s allocation; particularly
    regarding the inclusion of certain counties that are not afforded coverage under the
    Beach Plan in the “coast” zone, which is burdened by a greater share of the net cost
    of reinsurance and underwriting profit. The Commissioner also considered testimony
    of Department witness O’Neil, who took exception to Appel’s allocation.           O’Neil
    - 53 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    testified that she disagreed with the allocation of the net cost of reinsurance and
    underwriting profit to zones on the conceptual level because, “[f]rom an overall level,
    the Rate Bureau relates the amount of profit to the willingness of investors to supply
    capital. In that regard investors are only concerned with overall company profit, not
    the specific areas from which it may arise.” O’Neil also took exception to the inclusion
    of another level of simulation modeling to the Bureau’s filing and challenged the
    documentation and results of Appel’s model, noting that “the allocation of more than
    40% of the nearly $1 billion of underwriting profit, contingencies and Net Cost of
    Reinsurance to Zone 1a [was] unreasonable on its face.” In place of Appel’s model,
    O’Neil calculated the indicated rate level changes by territory.
    It is clear from the Commissioner’s findings that the Commissioner did not find
    Appel’s model and the resulting allocation of the net cost of reinsurance and
    underwriting profit reliable.        The Commissioner then rejected the Bureau’s
    allocation, finding as follows:
    468a. The Commissioner finds that the filed distribution
    of the net cost is discriminatory in that it is based on a
    Monte Carlo simulation of losses that appears to
    understate significantly the loss variance in the less
    hurricane prone areas by means of significantly
    understating the assumed annual variance in non-
    hurricane losses. According to the simulation file that was
    provided to the Department by the Rate Bureau (DOI-5,
    D.R 1.181-192), the arbitrarily assumed ratio of the
    standard deviation to the mean (known in statistics as the
    coefficient of variation (C.V.)) is approximately 1% for non-
    hurricane losses. Data provided on DOI-9, Schwartz
    - 54 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    prefiled testimony, AIS-18, shows that the state with the
    smallest annual coefficient of variation in its loss ratio
    among the 50 states has a C.V. of approximately 12%. The
    Commissioner finds that a Monte Carlo simulation that
    assumes a standard deviation relative to the mean for non-
    hurricane losses of 1% produces results that cannot be
    relied upon in determining overall risk by zone.
    469. Given Appel’s lack of credibility on this particular
    issue and the Bureau’s failure to recognize or address the
    fairness issue, the Commissioner herein orders that the net
    cost of reinsurance and underwriting profit will not be
    allocated to zones. Allocating the net cost and profit to
    zones as Appel recommends will result in rates that are
    unfairly discriminatory.
    The Bureau now challenges the Commissioner’s rejection of its allocation of the
    net cost of reinsurance and underwriting profit to zones because the Commissioner’s
    analysis went outside the record.            Specifically, the Bureau contends the
    Commissioner’s comparison of the coefficients of variation in finding 468a was not
    based on evidence in the record. Upon review of Exhibit DOI-9, AIS-18, to which the
    Commissioner specifically referred in finding 468a, we agree with the Bureau that
    the finding is not supported by evidence in the record. In response, the Commissioner
    does not direct this Court to any evidence supporting finding 468a, but instead
    contends that the Commissioner “used his expertise to analyze the data provided
    through discovery to determine that Appel’s simulation of losses cannot be relied
    upon.”     While that may be the case, without further findings regarding the
    Commissioner’s analysis and where the data relied upon may be found, this Court
    - 55 -
    IN RE: N.C. RATE BUREAU
    Opinion of the Court
    cannot determine whether finding 468a is supported by evidence in the record and
    must hold that it is not.
    We do, however, agree with the Commissioner’s further assertion that even if
    finding 468a is not supported by the record evidence, the Commissioner’s rejection of
    the Bureau’s allocation of the net cost of reinsurance and underwriting profit to zones
    is supported by the Commissioner’s other findings, which cast doubt upon the
    credibility of Appel’s model. The concerns raised in those findings concerning Appel’s
    credibility are supported by material and substantial evidence in the record. Thus,
    we affirm the Commissioner’s rejection of the Bureau’s filed allocation of the net cost
    of reinsurance and underwriting profit to zones.
    III.   Conclusion
    Upon a full review of the Commissioner’s order, we hold the order reflects a
    careful, thoughtful, and thorough consideration of the evidence. The evidence in the
    record supports the Commissioner’s critical findings and ultimate conclusions. This
    Court will not second guess the Commissioner’s determinations as to the credibility
    of the witnesses or the weight to be given their testimony. Therefore, the order of the
    Commissioner is affirmed.
    AFFIRMED.
    Judges DIETZ and TYSON concur.
